Short summary
Pressure coring is currently the only method that enables precise off-site analysis of gas and gas-hydrate volumes in marine sediments. Pressure barrels for sampling and preservation of submarine sediments under in situ pressure with the robotic sea-floor drill rig MeBo (MARUM, Bremen, Germany) were developed. Here we report on the design and operational procedure of the so-called MDP during two seagoing cruises and demonstrate functionality by presenting results from pressure core degassing.
